      iwlwifi: remove duplicate initialization · c3371d64
      Dan Carpenter authored
      rate_mask is initialized again later so this can be removed.  Btw, if
      rate_control_send_low(sta, priv_sta, txrc) returns false, that means
      that "sta" is non-NULL.  That's why the second initialization of
      rate_mask is a little simpler than the first.

      Bluetooth: Fix BT_L2CAP and BT_SCO in Kconfig · d45dcef7
      Gustavo F. Padovan authored
      If we want something "bool" built-in in something "tristate" it can't
      "depend on" the tristate config option.
      
      Report by DaveM:
      
         I give it 'y' just to make it happen, for both, and afterways no
         matter how many times I rerun "make oldconfig" I keep seeing things
         like this in my build:
      
      scripts/kconfig/conf --silentoldconfig Kconfig
      include/config/auto.conf:986:warning: symbol value 'm' invalid for BT_SCO
      include/config/auto.conf:3156:warning: symbol value 'm' invalid for BT_L2CAP

      since you can't export static functions.
